IMPROVEMENT IN HARROWS.

v Specification forming part of Letters Patent No. 184,199, datedNovember 7, 1876; application led May 4. 1876.

To all whom it may concern Be itknown that I, WILLIAM W. EDGEE- TON, ofWheeling, Livingston county, State of Missouri, have invented a certainnew and useful Improvement in Barrows, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, making part of this specitication.

This is an improvement on sulky-harrows.

My improvement consists, first, inthe form and construction of theharrow which works the whole surface of the ground, and is so made as topermit the operator to walk just in the rear of the axle. Thisconstruction does away with an elementof danger in wheelharrows-namely,the injury resulting from a fall backward from the seat-there being, linmy improvement, no part of the harrow extending back of the Seat at thelmiddle to such an extent as to endanger a person fall- The barrow ismade in two sections, connected together by hinges. In each section thebars containing the teeth are framed together in a V form, the apex ofwhich points inward, and between whose legs the wheels are located. Tothe end of the front leg of this V-frame (in each section) is attachedthe outer end of the front bar, and the inner end of the latter isconnected by an oblique bar to the end of the rear leg, and also to thefront 'barrow-sections and the draw-bar, so as to raise the harrow fromthe ground as the sectors are turned upward and backward.

Figure 1 is a perspective view of my mvention. Fig. 2 is a backelevation of the front hinge, connecting the two Sections. Fig. 3 is atop view of the rear-section hinge. Fig. A is a detail showin g theconnection of the drawbar to the harrow and to the lifting cord orchain. Fig. 5 shows the ratchet-sector, by which the draw-bar is raised,and the pawl for holding it back, and thus causing the continuedsuspension of the harrow.

A A are the ground-wheels, upon an axle, B. C is the seat; D, thetongue-hounds, and E the tongue. F. is a round rod or pin, extendih gdownward from the tongue, and which is stift'eued by aforwardly-inclined brace, F', extending from its lower end to thetongue, as shown. The pin or rod F passes through the draw-bar G, andthe draw-bar has vertical movement thereon. g is astaple at themidlength of the draw-bar, for the connection of the doubletree. Theends of the draw-bar are connected, by links H H, to the fore bars I Iof the barrow-sections, and the two bars I I are connected together attheir inner ends by a hinge, J. Each Section consists, beside the forebar l, of two oblique bars, K L, containing the teeth M, and a top bar,N, connecting the inner end of the bar l with the rear end of the bar L,and also Secured to the bar K. The bars K L are secured together at K',and

-extend outward from that point, inclining, re-

spectively, forwardly and backwardly, so as to give place for the wheelA between the ends. The two harrow-sections'are connected together bythe hinge J aforesaid and a hinge, O, at K'. The bar K of one sectionextends back past the hinge at 7c, and the bar l of the other sectionextends forward ot' the hinge at l, for the support of the teeth IWI. Pis a shaft,

having bearings at the rear of the axle, and

carrying three grooved sectors, Q QIQZ. R is a lever, by which the shaftO is turned in its bearings. The sectors Q and Q2 carry chains, whichlie in the grooves, and whose upper ends are attached to the sectors,and their lower ends to the bars N of'. the two harrow-l sections,respectively, so that as the sectors are rolled upward and backward thechains S are carried up by the sectors and raise the harrows. To thesector Q1 is attached the rear end of' a cord or chain, S', which passesthrough an eye, or over a pulley, T, beneath the tongue, and extends tothe draw-bar G, to

which the front end is attached, so that when the chains or cords S aredrawn upward the front end ofthe cord or chain S will be simultaneouslydrawn up, and thus, by moving the lever R backward, the harrow will beraised from the ground at ali parts.

When the harrow is raised the pawl U may be made to engage with theteeth q at the periphery of the sector Q1, so as to prevent the downwardmovement of the sectors, and so sustain the harrow in its elevatedposition.

I claim- 1. The barrow-section constructed of bars l K L N, arrangedtogetherlv substantially as described, in combination with the rod F anddraw-bar G.

3. The combination of the barrow-lifting chains or cords S S', sectors QQ1 Q2, shaft P, lever R, and draw-nar G, substantially as and for thepurpose set forth.
